Famous quotes containing the words labor and/or theory:
“The habits of our whole species fall into three great classes—useful labour, useless labour, and idleness. Of these the first only is meritorious; and to it all the products of labor rightfully belong; but the two latter, while they exist, are heavy pensioners upon the first, robbing it of a large portion of its just rights. The only remedy for this is to, as far as possible, drive useless labour and idleness out of existence.”
—Abraham Lincoln (1809–1865)
“Everything to which we concede existence is a posit from the standpoint of a description of the theory-building process, and simultaneously real from the standpoint of the theory that is being built. Nor let us look down on the standpoint of the theory as make-believe; for we can never do better than occupy the standpoint of some theory or other, the best we can muster at the time.”
—Willard Van Orman Quine (b. 1908)
